Purpose. The quality of electricity is a problem of major interest, making it necessary to
analyze the factors and causes that result in the worsening of the electric energy quality. An …

The paper presents an analysis of the power factor from a technical and economic point of
view. Power factor correction aims to improve power factor and therefore power quality by …

Purpose. Electrical equipment for explosion-threatening environments in mines at risk of
explosion communicates with the external environment through intrinsic safety barriers that …

The paper presents the structure of an active parallel filter for reducing harmonic pollution
and reactive power. The active power filter control is based on instantaneous reactive power …

The paper presents the structure of an active parallel filter for reducing harmonic pollution

The paper presents an analysis of the filtering and correction of the distorted steady state
power factor. Due to the example analyzed, it was observed that in the distorted steady state …

The paper presents an analysis of the operation of asynchronous motor drive systems. The
control method used is the vectorial one, being presented indirect and direct vector control …

This paper addresses a high-current field of research, under the conditions of proliferation of
nonlinear loads-generally static converters with power semiconductorsgenerating current …

The paper studies some aspects regarding asynchronous motor electric drives. In
connection with these categories of electric drives, it is proposed to develop a modern …

This paper aims to prove that the subject of transition to electric vehicles being a bad
decision concerning efficiency, is not founded on clear grounds. So it was shown in a …
